I've been "remapping" my channels with the clear QAM HDHomeRun, much
like most cable companies do now. For example, I remap channel 7 to
be 707 (the HD version). This way, it's easier to get to the HD
versions of the channels. I copy over the freqid, mplexid,
atsc_major_chan, etc, but when I do this with the HDHomeRun Prime,
MythTV still tells the Prime to tune the "regular" SD channel 7.
What else am I missing?
